This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (449f3c2c118d5a3da09aa1021397414752668851)
\
N -- N -- N (44b975a641c500c6d2ebdc7b7e3650ebba121d2d)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

osmo-bsc: react on reset requests from MSC
The bsc side currently can not receive reset commands from an
MSC. This patch adds required functionality to receive a reset
command and acknowlege it properly. The effects are the same
as with when sending resets (all drop all ongoing calls and
sccp connections)

libcommon-cs: genralize a interface reset fsm
The AoIP standard also describes an MSC->BSC reset procedure. We
currently do not implement it. However, the fsm that is used to
issue the reset request from the bsc side is not generalized. This
patch generalizes the code in order to be able to use the same
code on the MSC side to perform a reset procedure from there.

osmo-bsc: Send USSD notification when an MSC loss is detected
the old sccp-lite based imlementation offered support for sending
an USSD notification as soon as a loss of the MSC connection is
detected. This is done before forcefully dropping the affected
connection.
This commit ports the feature to the new libosmo-sigtran
implementation.
NOTE: I do not know if this works and I also do not really
understand how this is even possible. Sending an USSD notification
would rquire the subscriber to be properly attached? When the MSC
is lost this almost not possible since no backend to authenticate
against is available.

cosmetic: make function names in a_iface_bssap more expressive.

functions. This patch replaces the function names with more

Revert "mgcp: make sure all endpoints are closed on startup"
Clearing all endpoints by sending a DLCX on startup has ben found
to be a bit too offensive. It also will not help against
inconsitancies that may occour during runtime (e.g. an overheard
DLCX during regular call teardown).
This reverts commit b669ea94cb78fd9b56ee8dd9392538151349f8ba.

mgcp: Make sure endpoint is free on CRCX
The MSC is aware of the assigned endpoints at all times, so it
will not assign an occupied endpoint to someone else. However,
if it has just restarted, there maybe lingering open endpoints.
This patch introduces a fairly simple soultion. Before a new
endpoint is seized (CRCX), a DLCX is send in advance. If the
endpoint was still occupied with a dead connection, it will
be freed. If it was free anyway, the DLCX will just have no
effect.

a_iface_bssap: clear lingering subscriber connections on reset
When the BSC is vanishing, the subscriber connections will stay
active until the MSC is instructed via tha A interface to clear
the connections. Unfortunately, this will most likely not be
the case because the BSC will most likeley have lost all its
state and does not know about the old connections anymore.
This patch fixes the problem by looping through the list with
the active gsm subscriber connections and clearing them manually
when the reset from the BSC is received. Only connections by the
bsc who actually executes the reset are affected. Connections
from other BSCs will not be touched.

mgcp: make sure all endpoints are closed on startup
If the MSC is crashing and restarting, it may leave some endpoints
open. The endpoints can not be re-used until they are deleted
(DLCX). This patch sends a DLCX to all possible endpoints (usually
this is in a countable range) in order to clear possible open
endpoints from a previous run

mgcp: release no longer used endpoint identifiers
When an MGCP endpoint is deleted, we need to mark its endpoint
id as unused, so other calls can used it. This is currently not

mgcp: improve endpoint management
Currently the assignment of endpoint identifiers works by just
incrementing a counter. The mgcpgw only has a limited amount
of endpoint identifiers avaliable, this means we will run out
of endpoints after only a few calls.
This commit adds a mechanism to keep track of used endpoint
identifiers so unused endpoint identifiers can be re-used

mgcp: use mgcp DLCX command to terminate endpoint after call is done
Currently no DLCX command is sent to the mgcpgw when a call is over,
this leaves the endpoint open. This means that the endpoint can not
never be reused by other calls. This patch adds a DLCX that
terminates the the endpoint when the call is done.

osmo-bsc: Handle RESET/RESET-ACK properly
Improve the way the BSC executes its RESET/RESET-ACK sequence.
Currently only a simple bool variable serves as a state holder.
We set this variable to true when we receive the RESET-ACK
message. Unfortunately no further checking is done. This
patch replaces the old mechanism with a more elaborated
implementation which also detects a loss of the connection
and makes sure to reconnect properly afterwards. Also the
all open connections are closed on connection loss

osmo-msc: Integrate A interface into existing call control
The MSC already has some basic call control handling mechanism, that
was primarily used with 3G before. However, the already existing
code that handles the 3G calls is also perfectly fine for handling
2G calls. This commit integrates the A interface without breaking
it for 3G.

osmo-bsc: Negotiate rtp ip address/port with BTS
This patch adds the support for the RTP IP-Address/Port assignment.
The post communicated via the assignment request is now transmitted
via RSL/IPACC to the BTS. The Response containing the RX-Port at
the BTS side is communicated back to the MSC.
Since we plan to add a private MGCPGW to each BSC, this has to
be extended. Currently it only creates a direct connection to
the BTS. This will be introduced with a future patch.

libmsc: make pitfall in gsm0408_dispatch() more obvious
The function gsm0408_dispatch() accepts a message buffer pointer

message buffer, this may lead into a segfault if the user forgets
to set the l3h pointer. This commit adds assertions to popup a
more expressive error message.

WIP: Port to new libosmo-sigtran API (with proper M3UA for Iuh)
This changes over to the new libosmo-sigtran API with support for
proper SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for
the IuCS and IuPS interfaces.
Only the ASP (client) is used, assuming that both the HNB-GWs and RNCs
as well as the MSCs and SGSNs are all connecting as ASP to some STP/SGW
which offers M3UA server functionality as well as point-code and/or
global title based routing.

mgcp: hack RAB success from nano3G: patch first RTP payload
The ip.access nano3G needs the first RTP payload's first two bytes to read hex
'e400', or it will reject the RAB assignment. Add flag
patched_first_rtp_payload to mgcp_rtp_state to detect the first RTP payload on
a stream, and overwrite its first bytes with e400. This should probably be
configurable, but seems to not harm other femto cells (as long as we patch only
the first RTP payload in each stream). Only do this when sending to the BTS
side.

mscsplit: various preparations to separate MSC from BSC
Disable large parts of the code that depend on BSC presence.
Don't set msg->lchan nor msg->dst.
Don't use lchan in libmsc.
Decouple lac from bts.
Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication:
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to
different interfaces depending on the actual subscriber connection.
While iu_tx() is going to be functional fairly soon, the a_tx() is going to be
just a dummy for some time (see comment).
Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer
and an indicator for the Integrity Protection status on Iu (to be fully
implemented in later commits).
Add lac member to gsm_subscriber_connection, to allow decoupling from
bts->location_area_code. The conn->lac will actually be set in iu.c in an
upcoming commit ("add iucs.[hc]").
move to libcommon-cs: gsm48_extract_mi(), gsm48_paging_extract_mi().
libmsc: duplicate gsm0808 / gsm48 functions (towards BSC).
In osmo-nitb, libmsc would directly call the functions on the BSC level, not
always via the bsc_api. When separating libmsc from libbsc, some functions are
missing from the linkage.
Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also
add a _tx to gsm0808_cipher_mode():
* add msc_gsm0808_tx_cipher_mode() (dummy/stub)
* add msc_gsm48_tx_mm_serv_ack()
* add msc_gsm48_tx_mm_serv_rej()
Call these from libmsc instead of
* gsm0808_cipher_mode()
* gsm48_tx_mm_serv_ack()
* gsm48_tx_mm_serv_rej()
Also add a comment related to msc_gsm0808_tx_cipher_mode() in two places.
Temporarily disable all paging to be able to link libmsc without libbsc.
Skip the paging part of channel_test because the paging is now disabled.
In osmo-nitb, paging is done on BSC level and MSC level "at the same time".
When the new MSC is fully operational, paging will be controlled separately on
the MSC level, and the BSC (RNC) level will be instructed over an IuCS or
A-interface to negotiate paging with the MS (UE). This MSC level paging does
not yet exist and will be added in subsequent commits.
msc_compl_l3(): publish in .h, tweak return value. Use new libmsc enum values
for return val, to avoid dependency on libbsc headers. Make callable from
other scopes: publish in osmo_msc.h and remove 'static' in osmo_msc.c
add gsm_encr to subscr_conn
move subscr_request to gsm_subscriber.h
subscr_request_channel() -> subscr_request_conn()
move to libmsc: osmo_stats_vty_add_cmds()
gsm_04_08: remove apply_codec_restrictions()
gsm0408_test: use NULL for root ctx
move to libbsc: gsm_bts_neighbor()
move to libbsc: lchan_next_meas_rep()
move vty config for t3212 to network level (periodic lu)
remove unneccessary linking from some tests
remove handle_abisip_signal()

Use libvlr in libmsc (large refactoring)
Original libvlr code is by Harald Welte <laforge at gnumonks.org>,
polished and tweaked by Neels Hofmeyr <nhofmeyr at sysmocom.de>.
This is a long series of development collapsed in one patch. The original
history may still be available as branch neels/vlr_orig.
TODO: This commit may be split in several smaller changes before merging to
master.
SMS:
The SQL based lookup of SMS for attached subscribers no longer works since the
SQL database no longer has the subscriber data. Replace with a round-robin on
the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
subscriber is currently attached.
If there are many SMS for not-attached subscribers in the SMS database, this
will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
reveal that the subscriber is not attached, after which the DB is hit for the
next SMS. It would become more efficient e.g. by having an MSISDN based hash
list for the VLR subscribers and by marking non-attached SMS recipients in the
SMS database so that they can be excluded with the SQL query already.
There is a sanity limit to do at most 100 db hits per attempt to find a pending
SMS. So if there are more than 100 stored SMS waiting for their recipients to
actually attach to the MSC, it may take more than one SMS queue trigger to
deliver SMS for subscribers that are actually attached.
This is not very beautiful, but is merely intended to carry us over to a time
when we have a proper separate SMSC entity.
Introduce gsm_subscriber_connection ref-counting in libmsc.
